EDIT: Well IU was stuck here for ages but of course I figure it out ten minutes after posting this thread. Anyways, here is a text solution. Kind of vague, but it may help. Cheers.

You need to use the top left tentacle in combo with a bridge above the top spikes to pull the creature from the start to the right on the bridge, briefly release him, the capture again with left tentacle so he has energy to spring back to the left. As soon as you reattach him and he is coming back, move the bridge so it now ramps up to the top left light. The use the right tentacle to pull him through the middle (with a couple of ramps as buffers). Then while attached and hanging from the right tentacles, I make a ramp below right tentacle that leads to the rope and bottom middle light. With the momentum from rolling down this ramp, you can make it to the exit as well.

I've found an easier way to get the start:
place the top "ramp" over the top-most spikes, grab the creature with the left spring and as it's moving right grab it with the other spring, now wait for it to settle before moving the ramp.
point the top ramp towards the top-left orbs and release the right spring, the momentum should take you over the top of the ramp and into the orb
now you can continue the method mentioned in the top post
